直埋電纜敷設有哪些要求

直埋數據線敷設有哪個符合要求？（1）挖土的溝底是膨松的土壤，倘若是混凝土塊或硬性臟物要鋪100mm厚的軟土或砂層。纜線附進的泥士如內含耐腐蝕纜線金屬材質包皮，應處理和換土，埋深應不不低于0.7m，時光穿越農業用地時需要不不低于1m。在添加房建工程施工物、與地上房建工程施工物相互及避過地上房建工程施工物處，可淺埋，但應通過個性化會員服務維護保障保障措施，纜線應埋于凍持力層壤一下，當受先決條件局限時，應通過個性化會員服務防范纜線由于拉傷的保障保障措施。（2）電覽電線敷設后，上端要鋪100mm厚的軟土或沙子，再蓋起來水泥墊塊土確保英文板，擴大高度應超過了電覽電線雙側其它各50mm，或用磚取代水泥墊塊土確保英文板。
